This paper presents the results of a component-based model developed for an innovative type of connection, recently proposed by the authors, for beam-to-hybrid fabricated column (HFC) connections. The active constitutive components of the connection are identified and their relevant resistance and flexural stiffness are presented. The moment-rotation curve of the joint is reproduced using the assembly of these components. The failure point of the connection is also predicted using the failure modes observed in the experimental tests. The results obtained from the developed component-based model are then compared to those provided by a three-dimensional (3-D) finite element (FE) model and experimental tests. It is shown that the component-based model shows good accuracy in the prediction of the initial stiffness, rotation capacity and failure of the connection.
